CLOTHES-WASHER.

Specification of Letters Patent,

Application filed. March 18, 1911.

Patented Feb. 6, 1912. Serial No. 615,389.

To all whom it may concern:

Be it known that we, MARK G. EVANS and GEORGE W. LOGAN, citizens of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented new and useful Improvements in Clothes- VVashers, of which the following is a specification.

This invention relates to clothes washers or pounders, and has for an object to provide a pounder including a suction cup adapted to be manually operated in a suitable clothes receptacle, such as a boiler, tub or the like, and to be brought into effective contact with the clothes, the said cup embodying means for opening communication between the cup and the external air and to provide means for regulating the amount of air admitted to the cup when the device is in operation-so that the impact on the downward stroke of the cup or the suction on the upward stroke of the cup can be regulated in accordance with the Work upon which the device is used.

In the drawing, forming a portion of this specification and in which like numerals of reference indicate similar parts in the several views :-Figure 1 is a vertical section through our improved washing device. Fig. 2 is a horizontal section on the line 22 of Fig. 1.

Our improved washing device preferably comprises a substantially conical seamless cup 1 made of copper, zinc or any suitable well known material which may be found most desirable for the purpose intended. The large lower open end of the cup is formed to provide a peripheral reinforcing bead 2. The upper small end of the cup has secured thereto a socket member 3. This socket member is provided with an upper vertical portion which is of the same transverse diameter throughout, being adaptcd to be fitted to any suitable well known form of handle, (not shown). The socket member 3 forms a stop shoulder 4 and beneath the shoulder and embracing the apex or small end of the cup lis a regulating or controlling valve in form of a sleeve 5. This sleeve has formed therein a relatively long opening 6 which may be moved into coincidence with one or all of the intake openings 7 in the small end of the cup. The flared construction of the sleeve 5 prevents movement of the sleeve in a downward direction on the cup and the upward movement of the sleeve is limited through the provision of the stop shoulder 4;. The lower flared portion of the socket member 3 by embracing the small end of the cup reinforces the walls of the cup at this end and prevents the cup from splitting under the driving action of the handle into the socket member. The said socket member is preferably formed from a seamless body, but any suitable well known obvious means may be resorted to in the construction of the device.

The diaphragm 8 which is located interiorly of the cup preferably intermediate of the ends thereof is formed at its center with a relatively large depending substantially semi-spherical crown 9. The crown is of such a construction that the surface thereof which is exposed to contact with the clothes is curved throughout so as to prevent the clothes from adhering to the washer when the latter is in operation and it also eliminates the possibility of injury to the fabrics.

Considering the work to which our improved washer is adapted it is desirable as hereinbefore described to provide means whereby the impact on the downward stroke of the washer as well as the suction on the upper stroke of the same can be controlled to provide means for regulating the intake or discharge of the air to and from the washer. If the device is to be used for washing heavy coarse fabrics the valve 5 can be operated so as to entirely close the perforations 7, thereby cutting off the upper chamber 10 of the washer from the outside atmosphere when the washer is in perfect contact with the fabrics. This operation is of course governed best by the one using the device, but with the exercise of care the washer may be used with great success without injury whatsoever to the materials to be operated on. The crown 9 of the diaphragm is perforated, as at 11.

We claim A pneumatic clothes washer comprising a vertically disposed conical vessel open at one end, a perforated diaphragm positioned within the vessel intermediate the ends thereof, the upper portion of the said we sel immediately adjacent its end being provided with a series of transversely arranged openings with respect to the longitudinal alinement of the vessel, a conical valve revolubly mounted upon the vessel, said valve being formed to provide a transversely arranged elongated opening therein adapted In testimony whereof We aflix our signato be moved in coincidence With one or all tures in presence of tWo Witnesses. of the said openings in the vessel, a handle MARK G. EVANS. engaging member mounted on the upper end of the vessel the lower portion of the GEORGE LOGAN said member forming. a stop adapted to hold Witnesses: the valve against displacement from the ves- J.
